Material not physically examined. Multiple specimens in ZRC. Type of ‘ Hypoclinea sellaris ’, FOCOL2773 ( ZMHB).

Literature. Roger (1863) [as type of ‘ Hypoclinea sellaris ’]; Dill (2002).

Localities. Bukit Timah Nature Reserve; Lower Peirce Reservoir; National University of Singapore (Kent Ridge campus); Nee Soon; Pulau Ubin; Rifle Range Road; Sime Road; Ulu Sembawang Park; Upper Thomson Nature Park.

Habitat/Ecology. These ants were mostly found in disturbed secondary and wasteland forests, swamp forest, and also in an urban city park.

Remarks. A locally common and globally widespread tramp species, usually gregarious and numerous where it occurs. Probably a species complex ( Dill 2002), substantial morphological variation among different allopatric populations has been observed.At the time of writing, we treat these variants as conspecific until more compelling evidence for species delineation is made available in future. If more species are delimited from this complex, the perceived trampy nature of D. thoracicus may be disproved.
